[Immunoregulatory lymphocytes and circulating immune complexes in gastric cancer].

The characteristics of T-lymphocyte common population and their subpopulations, the level of circulating immune complexes and A, M, G immunoglobulins and the interaction between these items were studied in 75 patients with gastric cancer of clinical stages II-IV. The number of T mu-lymphocytes in patients with gastric cancer increased, that of T gamma-lowered. Correlation disturbances between these cells were observed. The level of circulating immune complexes and IgG increased. The disbalance as to immunoregulatory lymphocytes and its progress were followed by an increase in the content of circulating immune complexes.
